You should be able to find anything parts related on E-Bay, type in the info you put in here and do a search, you should be able to find it rather quickly

Mitsubishi 65 in Model 65909 DM Board replacement

There is not a replacement board available from Mitsubishi; you have two choices depending on problem: either a repair kit (widely available on the internet) or Contact PTS Electronics who will repair or rebuild it for you.

If you have questions let me know.

I have a convergence problem on my Mitsubishi 65 inch rear projection tv (model number WS65511). I see red double images on all four sides. Middle of the screen is OK. Which IC Mitsubishi use STK393-110...

Your model is the V21 chassis it requires the single IC STK393-110 you will also need 2 5 amp pico fuses. The convergence repair kit is available for your model at which contains the IC, heat sink paste, the pico fuses and the CD with repair instructions and other service info for that model.

Hi . My name is Paul. ws65 909 is about 12 yrs old. Have a yellow swoop front top right to top left, and there is double image on screen. Any ideas how to fix? Thx

Go into customer menu and select convergence, then advanced--if as I suspect it is skewed and will not adjust it is the convergence IC this set uses.

This model is one that uses just one chip for this---STK-393-110 and part is under 15 dollars on EBAY.

Good news: I have start to finish, step by step instructions for the do it yourself person for this repair in this set.

If you want the instructions we can find a way to get them to you, they tell you everything you will need and exactly how to do the repair.

If this information helped, rate this solution as very helpful as I do this for free.

Two blink code on this set means Usually one of the two pico fuses that protect the STK-393-110 CONVERGENCE IC is blown--the fuses will need to be tested and the chip and them replaced--

If you have enough skill I have step by step start to finish instructions for this repair in this set---set detects one of the voltages to the Chip is not there and shuts down instantly. I have photos of the chip, fuses and protect resistors this set uses also.

If you want the instructions for free give me a email and I will send them to you for free--if you are able to do this repair yourself you will save a lot of money--you can buy the chip on Ebay for about 14 dollars plus shipping and the same seller sells the pico fuses..............

If you want to attempt this give me a vote here--If you are not able to do it yourself I have suggestions for you about getting the set fixed--I have done hundreds of these sets!

Just reply to this post here.

Let me know what you want to do, I am here to help people

After about 3 minutes of my tv being on my convergence goes out of wack. I've tried to line it up but not all the lines will move back. Plus it works if I turn it off/on but only for a few minutes.

WS-65907 is a Mitsubishi 65 inch tv--it uses two STK-392-570 Convergence IC chips---I have repaired hundreds of these sets with this kind of trouble---the 570 Ic can be intermittent---You can buy two of them on Ebay for under 13 dollars plus shipping---this should be instantly fixable in your home---Get someone who is familiar with this kind of set; the center board inside has both of the IC chips on it; it needs to be removed and both IC chips replaced--all that is needed after that is to adjust the set with the Mitsubishi remote control---usually the whole repair takes about a hour in someone's home---I know----I do this on a regular basis---if you have any questions or need direct help of any kind contact me at my email---- this has been helpful I would appreciate a vote from you here.
